Product warranty
Advantech warrants to you, the original purchaser, that each of its
products will be free from defects in materials and workmanship for
one year from the date of purchase.
This warranty does not apply to any products which have been
repaired or altered by persons other than repair personnel authorized
by Advantech, or which have been subject to misuse, abuse, accident
or improper installation. Advantech assumes no liability under the
terms of this warranty as a consequence of such events.
If an Advantech product is defective, it will be repaired or replaced at
no charge during the warranty period. For out-of-warranty repairs,
you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, type of PC, CPU speed, Advantech products used, other
hardware and software used, etc.) Note anything abnormal and list
any on-screen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your
manual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return
material authorization) number from your dealer. This allows us to
process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair and
Replacement Order Card and a photocopy proof of purchase date
(such as your sales receipt) in a shippable container. A product
returned without proof of the purchase date is not eligible for
warranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

Initial Inspection
Before you begin installing your card, please make sure that the
following materials have been shipped:
• 1 PCA-6168 socket 370 Intel Celeron®processor-based single board
computer
• 1 Intel Celeron®processor, and 1 cooling fan (optional)
• 1 PCA-6168 User's Manual
• 4 utility disks/CD with VGA BIOS (PCA-6168/6168E/6168S/
6168F only)
• 2 Ethernet driver disks/CD (PCA-6168E/6168F only)
• 1 SCSI driver disk/CD (PCA-6168S/6168F only)
• 1 bus master utility driver/CD
• 2 disks/CD for OBS Win95 drivers
• 1 FDD cable
• 2 EIDE HDD cables
• 1 printer (parallel port) cable
• 1 temperature sensor cable
• 1 ivory cable for keyboard and mouse
• 1 SCSI cable (PCA-6168F/6168S only)
• 1 USB cable (optional)
• 1 ATX-to-PS/2 power cable
If any of these items are missing or damaged, contact your distributor
or sales representative immediately.
We have carefully inspected the PCA-6168 mechanically and
electrically before shipment. It should be free of marks and scratches
and in perfect working order upon receipt.

As you unpack the PCA-6168, check it for signs of shipping damage.
(For example, damaged box, scratches, dents, etc.) If it is damaged or
it fails to meet the specifications, notify our service department or
your local sales representative immediately. Also notify the carrier.
Retain the shipping carton and packing material for inspection by the
carrier. After inspection, we will make arrangements to repair or
replace the unit.

CHAPTER

2 PCA-6168 User's Manual
1.1 Introduction
The PCA-6168 Series all-in-one industrial grade CPU card uses
Intel's highly acclaimed Celeron®processor, together with the Intel
440BX PCI chipset. The card works with standard ISA or
PCI/ISA-bus passive backplanes.
The CPU provides 128 KB on-CPU L2 cache, eliminating the need
for external SRAM chips. It has two PCI EIDE interfaces (for up to
four devices) and a floppy disk drive interface (for up to two devices).
Other features include two RS-232 serial ports (16C550 UARTs with
16-byte FIFO or compatible), one enhanced parallel port (supports
SPP/EPP/ECP) and one USB (Universal Serial Bus) port. The PCI
enhanced IDE controller supports Ultra DMA/33 and PIO Mode 4
operation. This provides data transfer rates of over 33 MB/sec.
System BIOS supports boot-up from an IDE CD-ROM, SCSI
CD-ROM and LS-120.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 63-level
watchdog timer, which resets the CPU or generates an interrupt if a
program cannot be executed normally. This enables reliable operation
in unattended environments.
The PCA-6168 series offers several impressive industrial features
such as a VGA (AGP) controller, a PCI Ultra2 SCSI controller, a
10/100Base-T networking controller, three DIMM slots for a total of
768 MB RAM memory, and an ISA High Drive. In addition, the
PCA-6168 series supports a solid state disk (SSD) using M-Systems
Corporation's DiskOnChip®2000 Flash disk, for up to 144 MB of
non-volatile, reliable memory that is not vulnerable to the hazards of
an industrial computing environment. All these make it an ideal
choice for applications that require both high performance and full
functionality.
Note: Some of the features mentioned above are not
available with all models.For more information about
the specifications of a particular model, see Section
1.3:Specifications.
